I have this wonderful book, Readers Digest "1,000 Great Quilting Designs for hand or machine stitching" ISBN 0-7621-0490-2
Available from rd.com.
My brother bought it for me for my birthday. It starts with telling you how to set up a design, and then offers placement suggestions, and then has 1,000 designs, it even tells you if these are better for the machine or by hand and how to magnify for the best fit.
I highly recommend it.
